Feb 11, 2008
The answer to any question regarding what is a Blu-ray disc is best given by describing it as being a futuristic optical disk that is poised to take over the home entertainment industry and more particularly is a worthy alternative to DVDS. In fact, the Blu-ray disc has really been developed by a number of international manufacturers of electronic items that have pooled their resources and formed what is known as the a Blu-ray Disc Association or BDA which includes big names such as Apple, Hitachi, Dell, JVC, HP as well as many others.

Five Times The Storage Capacity Of DVDs

Another feature that is sure to come to your notice when considering what is a Blu-ray disc is that it has as many as five times the storage capacity as is found in a DVD and a single Blu-ray disc can hold as much as fifty GB of data. The answer to what is a Blu-ray disc is also found in its primary use, which is of storing high-definition movies though it is also very useful in storing high volumes of data, and it also still does look much like any ordinary DVD disc does, which means that you won't really notice any physical difference in the Blu-ray disc when comparing them to DVD discs.

Blu-ray discs are thus of the same size as DVDs and so any player that is capable of playing Blu-ray discs will also be able to play DVDs and also CDs. However, a difference between what is a Blu-ray disc and what DVDs and CDs are lies in the color of the laser used for Blu-rays which is blue as opposed to the red laser used in the case of DVDs and also CDs.

Most people, when they wish to know a lot more about what is a Blu-ray disc will also wonder as to what the benefits of using blue ray lasers are as compared to using red lasers, and for them the answer lies in the fact that blue lasers have shorter wavelengths, thereby providing greater accuracy as compared to red lasers which have a longer wavelength. This, in turn means that the answer to what is a Blu-ray disc, shows that with Blu-ray discs you get far greater precision when storing data and thus a Blu-ray disc of the same size as a DVD can store far greater amount of data.

Furthermore, having once learnt about what is a Blu-ray disc, you would immediately realize that this storage capacity of fifty GB of data on a single Blu-ray disc has opened up some serious new vistas in mass storage, which when combined with the fact that it is now possible to record HD DVD movies and audios better with a Blu-ray disc means that you are assured that it will serve the needs of a much greater number of people that have switched over to watching high-definition programs and who thus are ready to use the best recording media available today.
